Thermal entropy
Hello, I was needing some clarification on Thermal entropy. From what I understand, it is the probability of a system to be in a specific state based on the movement of molecules or atoms in a constant volume. Could someone comment on my definition if there is anything that I am misunderstanding or omitting?

Re: Thermal entropy
Hello! Yes, your definition of thermal entropy is exactly right. Thermal entropy differs from positional entropy, or the number of different physical arrangements that are possible. Positional entropy is often described and visualized in a system imagined to be at absolute zero (0 K) exactly because in this state, there is no thermal entropy. I hope this helps!

Re: Thermal entropy
Another thing about thermal entropy is that it is dependent on temperature and will no longer be present at absolute zero
